Abstract Recent studies have shown that functional connectivity can be decomposed into its exact framewise contributions, revealing short-lived, infrequent, and high-amplitude time points referred to as ``events.'' Although events contribute disproportionately the time-averaged pattern, improve identifiability brain-behavior associations, been linked endogenous hormonal fluctuations autism, their origins remain unclear. Here, we address this question using two independently-acquired imaging datasets in which participants passively watched movies. We find synchronize across individuals based on level of synchronization, categorized three distinct classes: those at boundaries between movies, during do not all. boundary events, compared other categories, exhibit greater amplitude, co-fluctuation patterns, temporal propagation. show underlying is a specific mode involving activation control salience systems alongside deactivation visual systems. Finally, strong positive relationship similarity time-locked patterns propensity for frames involve synchronous events. Collectively, our results suggest spatiotemporal properties are non-random locked time-varying stimuli.

Classroom teaching is essential for cognitive development and cultural evolution, yet its neurocognitive mechanisms remain unclear. Here, this explored in a university graduate course by combining wearable functional near-infrared spectroscopy (fNIRS) machine learning models. The results show that blended involving both students' recalling teachers' lecturing leads to better outcomes than alone. Moreover, during the same phase, induces knowledge construction middle frontal cortex (MFC), while alone representation right temporoparietal junction (TPJ), with former significantly correlating final outcomes. Additionally, MFC's begins earlier but facilitated later lecturing. Finally, when teacher's TPJ activity precedes of MFC, significant teacher-student neural synchronization observed correlated These findings suggest that, real classroom teaching, MFC serves as hub rapid cortical process, supporting through projection from TPJ.

Recent studies demonstrate that the brain parses natural language into smaller units represented in lower-order regions and larger higher-order regions. Most of these studies, however, have been conducted on unidirectional narrative speech, leaving linguistic hierarchy its cortical representation bidirectional conversational speech unexplored. To address this gap, we simultaneously measured activity from two individuals using functional near-infrared spectroscopy (fNIRS) hyperscanning while they engaged a naturalistic conversation. Using Pre-trained Language Model (PLM) Representational Similarity Analysis (RSA), demonstrated jointly produced by interlocutors turn-taking manner, exhibits hierarchy, characterized boundary effect between an incremental context effect. Furthermore, gradient pattern shared was identified at dyadic rather than individual level. Interpersonal neural synchronization (INS) left superior temporal cortex associated with turn representation, whereas INS medial prefrontal linked to topic representation. These findings further validated distinctiveness different sizes. Together, our results provide original evidence for underlying architecture during conversation, extending hierarchical nature speech.

Human neuroimaging studies of episodic memory retrieval routinely observe the engagement specific cortical regions beyond medial temporal lobe. Of these, parietal cortex (MPC) is particular interest given its distinct functional characteristics during different tasks. Specifically, while recognition and autobiographical recall tasks are both used to probe retrieval, these paradigms consistently drive spatial patterns response within MPC. However, other have emphasized alternate MPC dissociations in terms brain network connectivity profiles or stimulus category selectivity. As unique contributions remain unclear, adjudicating between accounts can provide better consensus regarding function. Therefore, we a precision-neuroimaging dataset (7T magnetic resonance imaging) examine how differentially engaged task-related may also reflect profiles. We observed interleaved, though spatially distinct, subregions where responses were sensitive either decisions semantic representation stimuli. In addition, this dissociation was further accentuated by displaying with hippocampus task rest. Finally, show that recent observations dissociable person place selectivity category-specific from identified mnemonic demands. Together, examining precision mapping individuals, data suggest previously conform common principle organization throughout hippocampal-neocortical systems.

Abstract Humans have an outstanding ability to generalize from past experiences, which requires parsing continuously experienced events into discrete, coherent units, and relating them similar experiences. Time is a key element in this process; however, how temporal information used generalization remains unclear. Latent-cause inference provides Bayesian framework for clustering by building world model related experiences are generated shared cause. Here, we examine latent-cause inference, using novel task participants see “microbe” stimuli explicitly report the latent cause (“strain”) they infer each microbe. We show that humans incorporate time their of causes, such recently inferred causes more likely be again. In particular, “persistent” model, one observation has fixed probability continuing next observation, explains data significantly better than two other time-sensitive models, although extensive individual differences exist. our good psychometric properties, highlighting potential use quantifying computational psychiatry or neuroimaging studies.

"Sherlock" seventeen first half episode BBC's Sherlock (48 minutes). viewing, then verbally described what they remembered about movies in own words. Participants' speech was recorded using an MR-compatible microphone. The audio recordings were transcribed, timestamped by a forced aligner; missing filled manually transcriptionists referencing recording. Each file contains participant's recall word word, onset each seconds with 1/10th-second precision, and corresponding volume number (TR). This dataset can be used investigate topics such as naturalistic memory language production.
